I have a set of 20" BBS RE forged aluminum monobloc wheels complete with Bridgestone RE050 tires for sale.

Wheels are 20x9" wide, +13 mm offset on the front, and 20x10" +20 mm rear. They are fully FORGED, very strong, and lightweight, in fact I have never lifted a lighter 20" wheel. I think they weigh less than 25lbs a wheel!
These wheels are very very rare, I don't recall ever seeing another set for sale here.
All 4 wheels are straight and true with the original diamond silver finish from BBS. Only blemish is an approximately 3" curb mark located on the rear passenger wheel, it could very easily be refinished for under $100. Other than that the wheels are in like mint condition.

Tires are Bridgestone Potenza RE050 255-30-20 front and 285-30-20 rears. Front tires have 7/32 thread and the rears about 6/32 left on them. The tires not only handle amazing, but the ride paired with KWV3s actually felt better than on stock suspension with OEM 19" wheels.
